Monospace product identifiers

Renders offer and item identifiers in a fixed-width font so they are easier to compare and spot typos in.

table td a[href*="offerId"], table td a[href*="itemId"],
[aria-label*="item id" i] {
  font-family: "Roboto Mono", "Consolas", monospace !important;
  letter-spacing: 0.2px !important;
}
